There are many places on this Earth that humans just aren’t meant to be in. They are nightmarish glimpses of hell and horror that should be tucked away and stay that way. But, if you’re feeling brave (or insane) it would be easy to visit any of these places on this list.

Although, they just make us feel a whole lot of NOPE.

1. The Door to Hell, Turkmenistan: The large, fiery pit was originally a gas field that was set on fire by Soviet scientists, because they thought that’d be a fine idea. It has been burning continuously now for over 40 years.

For some reason, spiders are drawn to this real-life Hellmouth and swarm there by the thousands. We think because of the evil.

2. Island of the Dolls, Mexico: This place is a mostly uninhabited island in Xochimilco, Mexico. According to the legend, a girl died in the canals surrounding the island.

After her death, dolls began to wash ashore. Then, the one inhabitant began hanging the dolls as a tribute to the deceased child.

3. Centralia, Pennsylvania: Centralia is the real-life Silent Hill (and the movie was based on this location, right down to the creepy church). It was once a mining town until the coal veins under the city accidentally caught fire.

The mines have been burning continuously since 1962.

4. Muynak, Uzbekistan: Muynak was once a busy port city on the Aral Sea.

The Soviets unintentionally drained it while creating irrigation. Today, the skeleton boats still sit on the dry sea bed.

5. Kabayan Mummy Caves, The Philippines: These manmade caves are full of some of the most well-preserved mummies in the world.

They are isolated in a remote mountain. They are filled literally to the brim with corpses.

6. Kryziu Kalnas, Lithuania: The “hill of crosses” was once a ceremonial site where Lithuanians would mourn their dead lost at war.

The Soviet Union bulldozed it twice, only for the locals to build it even bigger. There are over 100,000 crosses there today.

7. Cincinatti’s Subway, Ohio: In the early 1900s, Cincinatti attempted to build a subway system, but they ran out of funding.

The empty tunnels still exist, half-way finished and running along the underbelly of the city.

8. Akodessewa Fetish Market, Togo: Over half of the population in Togo continue to practice indigenous beliefs, they have a market specifically for those beliefs.

You can find dead animals, bones and mysterious concoctions. Travelers should probably avoid said market.

9. Wonderland, China: The Chinese government attempted to build a Disneyland-like theme park, but much larger. They faced construction problems and the project was trashed.

The remains of the theme park are still standing today, completely open to anyone brave enough to visit.

10. The Catacombs of Paris, France: The Parisian Catacombs hold approximately 6 million bodies. The space spans the entire city, full of macabre scenes.

It’s the city beneath the city… but it’s for the dead.

Sometimes, it’s best just to let places be. Especially if they have been touched by evil. Or Soviets.
